Detailed Description

Parsing and resolution for the URLs the HTTP and WebSocket transports dial.

Three transports each grew a private copy of this (the SSE client, the WebSocket client, and the WebSocket signalling client), and a fourth caller – following a Location header while downloading – needs reference resolution none of them had. One parser serves them all.

The scope is limited to absolute http/https/ws/wss URLs with an authority, plus the relative forms a redirect may answer with. This is not a general RFC 3986 implementation – there is no userinfo, no percent normalisation, and no dot-segment removal beyond what ResolveReference needs.
